Key Parameters

Substitute Part Grouping Explanation

Substitution of the Grayhill 97R02S is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit configuration (SPST), number of positions (2), current rating (25mA), and voltage rating (24VDC) must be identical.

Mechanical Parameters: Actuator type (Slide Standard), actuator level (Flush, Recessed), mounting type (Surface Mount), termination style (Gull Wing), and pitch (0.050" Half) must match exactly.

Physical Dimensions: Height above board (0.061"), length (0.148"), and overall form factor must be preserved for PCB layout compatibility.

Material & Environmental Specifications: Contact material (Copper Alloy), contact finish (Gold), body material (Polyamide/Nylon), operating temperature range (-40°C to 85°C), and washability must be maintained.

The Grayhill 97R02ST meets all these criteria and qualifies as a direct substitute for the obsolete 97R02S.

Parameter Comparison

Engineering Selection Recommendations

The Grayhill 97R02ST is the direct substitute for the obsolete 97R02S. All electrical, mechanical, and dimensional parameters are identical, ensuring functional equivalence in circuit applications.

Product Status Consideration: The 97R02S is classified as obsolete, while the 97R02ST maintains active product status with current manufacturing support and availability. This transition is necessary for long-term supply chain reliability.

Compliance Advantage: The 97R02ST achieves ROHS3 compliance, whereas the 97R02S is RoHS non-compliant. For applications subject to RoHS regulations, the 97R02ST provides regulatory alignment without functional compromise.

Packaging: The 97R02ST is supplied in Tube packaging, compared to the main part specification. Packaging format does not affect electrical or mechanical performance and is determined by procurement and assembly requirements.

Inventory & Availability: The 97R02ST maintains significantly higher inventory levels (5,690 pieces) relative to the 97R02S (997 pieces), supporting consistent procurement and production scheduling.

Frequently Asked Questions (FAQ)

Q: Can the 97R02ST directly replace the 97R02S in existing designs?

A: Yes. The 97R02ST is electrically and mechanically identical to the 97R02S across all critical parameters including circuit configuration, current/voltage ratings, actuator type, mounting style, and physical dimensions. No design modifications are required.

Q: What is the primary reason for substitution?

A: The 97R02S is classified as obsolete. The 97R02ST is the active equivalent from the same manufacturer (Grayhill Inc.) and series (97), ensuring continued availability and manufacturing support.

Q: Does the RoHS compliance difference affect compatibility?

A: No. RoHS compliance is a regulatory and material composition attribute. The 97R02ST's ROHS3 compliance provides enhanced regulatory alignment for applications subject to RoHS directives, but does not alter electrical or mechanical function. Both parts operate identically in circuit applications.

Q: Are the physical dimensions identical?

A: Yes. Both parts share identical height above board (0.061"), length (0.148"), pitch (0.050" Half), and all other dimensional specifications. PCB layout and footprint compatibility is preserved.

Q: What is the difference in packaging?

A: The 97R02S specification does not define packaging format, while the 97R02ST is supplied in Tube packaging. Packaging format affects logistics and assembly handling but does not impact electrical or mechanical performance.

Q: Are the contact materials and finishes the same?

A: Yes. Both parts feature copper alloy contacts with gold finish, ensuring identical electrical performance, corrosion resistance, and washability characteristics.

Q: Is the operating temperature range the same?

A: Yes. Both parts operate across the identical temperature range of -40°C to 85°C with identical mechanical life rating of 1,000 cycles.

Q: What certifications apply to both parts?

A: Both parts share identical REACH Unaffected status and EAR99 export classification. The 97R02ST additionally achieves ROHS3 compliance. Both maintain MSL 1 (Unlimited) moisture sensitivity rating.
